1H openings with modified Kaplan Inversion
- The really good one suited hands are opened 2 ♣ (8 tricks, 6 card suit, 5 controls)
- The strong two suiters (4 losers or less) are opened with MisIry transfers
- The long suit, strong hand, not suited for 2 ♣ are opened with namyats
- The "strong" three suiters (5-4-4-0) are opened 2 ♣
- The "strong" balanced hands are opened 2D (22-24), or 2 ♣ (25+)
- Weak hands with five plus major and 4+ clubs are opened 2M
This means that an opening bid is limited to less than each of those possible holdings. This has important implications for the subsequent auctions, especially opener's rebids.
Over one of a major, we play a semi-forcing 1NT but with modified Kaplan inversion, invitational jump shifts, and a specialized inverted drury after a first or second seat opening bid. Two notrump by either partner is often a game try in the other partners major. But this post deals with how Modified Kaplan Inversion along with Riton 2♣ are used after a 1♥ opening bid. Here is the scheme, first with what is unique to 1H opening bid.
Unique Auctions related to Modified Kaplan Inversion
Normal Kaplan Inversion is fairly simple. After a 1♥ opening bid, responder bids 1♠ with 0-4 spades and a hand unsuited for another bid, and bids 1NT with 5+♠. Opener's rebids are 1NT showing a minimum hand with 11-15 and 4♠s, and new minors as better minor. Inquiry 2/1 modifies this. We use responders 1♠/1NT as per normal, but opener's rebid varies from standard a little depending upon rather the initial response was 1♠ or 1NT.
First, over 1♠, we will rebid 1NT with all weak balanced hands lacking four card spade suit. A 2♦ rebid by opener promises 4♠'s, so a 1NT rebid also includes hands with 4♦'s), 2♣ rebid is Riton ♣, showing a good hand of 15HCP or more. Over a 1Spade response, a jump to 2NT shows BAL 20-21 HCP.
Over responders 1NT, 2♠ is a simple raise, and may be with three card support. And over 1NT, 2NT is "Jacoby 2NT by opener" showing four card support and game invite stregth". Over 1♠ by responder, spades have not been promised, so 2♠ is a true reverse, and in fact, shows 5♠/6H's. Ritong 2C followed by 2♠ (if given an opportunity) shows four card spade suit and good hand. Jumps to 3♣/3♦ are true two suiters, 5-5 or better.
If responder bid 1S which denies five+ spades and three hearts, 2NT can no longer the "Jacoby 2NT by opener" because partner hasn't promised spades.
1H -- 1S = Modified Kaplan Inversion
| 1NT | Balanced hand with 3S or few spades, or unblanced with 4 diamonds. Always weak. |
Pass: | |
2C --> To play | |
2D: --> To Play | |
2H: To play | |

2NT: GI without four spades, balanced | |
| 2D | Five hearts, four spades, minimum hand |
Pass: To play | |
2H: weak preference, clearly a doubleton | |
2/3/4♠ To play or invite | |
2NT Transfer to 3C (like on stayman auctions) | |

3C/3D weak bids, long suit | |
Modified Kalplain Inversion after | |

3H: slam try | |
3S: Great spades, forcing (to invite in spades, bid 2S then rebid 3S) | |
| 2S | Three or four card support, weak hand |
2NT: check back, opener bids 3C/3D to complete distributional picture with shortness in other minor. Rebids 3H to show 3532, minimum, rebids 3s to show 4522 minimum, rebids 3NT to show 4522 maximum. | |
3C/3D/ forcing, cue-bid | |
3H: two suit trump fit, start cue-bidding (if blackwood is used, 6 key cards) | |

minor raise: invitational | |
All others, GF, including 3S rebid | |
| 4C/4D | Splinter, no control in "other minor" |
4S: to play | |
4H: Last train, promise control in other minor | |
4NT: Roman Keycard Blackwood | |
| 2C | Ritong 2C (may have three card support) |
PASS: Extremely rare, clubs is responder suit, weak hand | |
2D: waiting now | |
2H: warning, weak hand | |
2S: real spades, weak hand, unsuited for 2S preempt (probably five only spades) | |
| 3H | Great suit (one loser opposite singleton), unsuit for acol 2C opening |
Pass to play | |
3NT: to play | |
3S: general force, not a cue-bid | |
4C: forcing, cue-bid (may have spade control) | |
4D: forcing, last train (lacks club control) | |
The disadvantage of this system, is the 1H-1NT is now forcing, whereas other systems might have an auction that goes 1H-1S-1NT all pass. Exceot for that auction, we gain precision on bidding of all other auctions. The trade off, is we can get into 1NT on auctions that go 1H-1S-1NT where other 2/1 GF auctions begin 1H-1NT (forcing).
Not discussed above is the unexpected opener rebid of 3NT over 1 level responses. This shows 20-21 balanced if new MisIry is being played (where 2NT opening is preempt in clubs or strong in hearts and a suit other than clubs).
Let's examine some hands to see who riton 2C and other methods described above work after a 1H opening bid.

Hands where RESPONDER does not have SPADES
Note, when you limit partner to 2 or fewer hearts (or raise hearts directly) and 3 or less spades, that means fewer hands to choose from. These hands are fairly rare.
- Responder must be too weak for 2/1 GF
- Responder must not be suitable for invitational jump to 3 of minor
- Respnder can not be "balanced" 11 plus
- Responder must have enough hcp to want to bid

Please explain what opener does with 2-5-3-3 shape after the auction 1H-1S.
1NT shows 3 spades, 2C is strong and 2D shows 4 diamonds. Seems you're stuck!
Han
Typo: In the last paragraph before the green stuff you say that 1H-1S denies 4 spades. It does not, it denies 5 spades.
Han
Thanks for catching the typos, afraid i type too fast and my eyesight is not what it should be, so i make a lot of those. reporting them always appreciated :-)
Now to being stuck with 2-5-3-3 if partner bids 1S (not 1NT).
Ok, you are only "stuck" if you opened a 11-13 hcp hand. If you had 14-16, you would have opened 1NT. If you have 16 or more, easy 2C rebid.
So now you have some trashy 13 or less hcp hand. Something like, S-xx H-KQxxx D-Axx C-Kxx. Here, like always, you have to tell the best lie. One option is to rebid 2H, one is to bid 1NT, one is to create a fourth diamond with 2D. This is hardly worse than standard 2/1 GF after 1H-1NT (where they can not pass). Nor is it too different from standard 2/1 with 4S and 5H and 2-2 in the minors and partner bids 1NT. Stuck? Well yes. Three strong diamonds, bid 2D, five strong hearts, bid 2H. Those are options one and two, I lean towards 2D if no clear choice.
